Laminated documents

One of the important aspects of the development of P-plastomers was the expectation that these materials were amenable to plastics processing such as fiber and film formation and yet would yield soft elastic fabrication. This combination was hitherto unknown [24]. The formation of nonwoven fabrics including spun-bond and melt-blown nonwoven fabrics as well as their laminated forms has been documented. Similarly, cast film operation to form elastic monolithic films or composite structures which are not only amenable to these processes, but also to a variety of postfabrication processes have been described. 

The occurrence of voids has been thoroughly documented in thick laminates [2], In almost all cases, they are apparently associated with the prepreg surface. The exact mechanism of void formation depends on the system, but in the most general case it can include mechanical entrapment as well as nucleation of stable voids in the resin phase.

Barrow, who was developing cellulose acetate lamination as a method of preserving documents, took the step of applying the bicarbonate solutions to the preservation of acid papers, both those still with adequate strength and those weak and requiring lamination. According to Clapp...

The tendency to have a pack component specification which is all-embracing is also changing. A simpler procedure utilises a series of information documents which lay out the procedures that a supplier has to follow for selective package forms, i.e. glass bottles, plastic bottles, laminates, labels, collapsible tubes, etc. It is then possible to have an abbreviated specification document which covers critical, major and minor defect classifications, advice on delivery and identification, and basic information on the material to be employed, etc. The specification therefore cross-references to its respective information (component manual) document and becomes considerably simplified in terms of both layout and detail. This is particularly important now that specifications are being computerised in conjunction with stock control and purchasing. 

It is now fairly normal procedure to have a general support document, i.e. packaging material manual, issued under specific headings such as bottle glass bottle plastic laminations labels leaflets. These broadly describe the requirements of the items including reject (defect) terminology and possibly associated AQL. Such manuals provide suppliers with a broader view of the quality expected, and may cross-reference the details of the test procedures, including performance, to be applied (see below). 

Batch testing is carried out to verify prepreg properties, such as resin content, volatile level, and flow. The resin advancement (chemical reaction) is monitored via a Differential Scanning Calorimeter (DSC) and the formulation consistency by testing the Tg via DSC or Dynamic Mechanical Analyzer (DMA). The laminate properties are also determined. All are documented and quoted on a Release Certificate. 

Hodgkinson s work made and still makes many debates obsolete certain assumptions such as focusing on the extruder as the notorious creator of laminations had to be reconsidered and many patent cures documented in the literature revealed themselves on the basis of this work to be of no general use, only offering a suitable solution in individual cases. Hodgkinson was able to prove with the use of a highly sophisticated test device, which was ahead of its time, that the formation of flow laminations within... 

Both methods introduce a density and viscosity gradient between the suspension and the spin fluid. The gradient cushions the hydrodynamic shock of the particles as they enter the spin fluid and, thus, produces a smooth transition, ensures laminated flow and avoids streaming. The pros and cons of line start vs homogeneous start are well documented in the literature. Good results using the line start method are reported for the Joyce Loebl, Horiba Capa 700 and Brookhaven B1 DCP instruments. 

The polymer that forms is crosslinked, but spectroscopic analysis shows that 90% of the monomer placement is through ring formation. Formation of six-membeied rings is also well documented. Two examples were shown above in the polymerization of a quaternary diethyldially-lamine and in the polymerization of 2,6-disubstituted, 1,6-heptadiene. Many other 1,6-heptadienes yield linear polymers containing six-membered rings. " ... 

In the middle of the 20 century some museum quality documents have been displayed by laminating them between sheets of cellulose acetate. The Declaration of Independence written by Thomas Jefferson in 1776 is one such document. In 1947, this document was laminated between two... 

Laminated plates form one of the basic structural elements for the use of composite materials. In this document laminated plates are defined as Plates Type I, II or III, depending on the degree of directional homogeneity of their material properties. 

Lamina and laminate strengths are dealt with simultaneously in this document. The strength of a laminate is a function of the strengths of its laminae.
